Aim: To compare the translucency of three recently introduced esthetic zirconia, Argen Z Anterior (Argen Corporation), Ceramill Zolid FX (Amann Girrbach AG), and Prettau Anterior (Zirkonzahn), with that of a commonly used esthetic ceramic material (lithium disilicate), IPS e.max CAD LT (Ivoclar Vivadent). Materials and methods: The three partially sintered zirconia materials were sectioned using a low-speed water-cooled diamond saw into a square shape, and the final dimensions of [10.0 × 10.0 × 1.5 mm] (n=10/group) were acquired after sintering. As a reference group, the partially sintered lithium disilicate (IPS e.max CAD LT) blocks were sectioned and sintered into similar shapes and dimensions. Then, all samples were finished and polished. The CIE L*a*b* values for each sample were measured on a black and a white background usi.. Read More»
